How can I fix broken chipboarb on the wardrobe?

yes there are two ways to fix this problem fill the hole with a car filler mix let it harden then re drill hole, or you can fill with a good glue and re hang the hinge right away. just thought of a way we always used plug hole with a wood plug glued in leave to go hard trim plug if needed when dry. re drill hole or holes re insert the screws this way the screw pushes the sides of the wood to sides of the hole/s and holds on tight should be ok. if there is room ether side of the screws try drilling through then insert two new screws not the same size as the ones broken to do this you really should know what you are doing stick to above if you are not to sure.
